Product Description

Genset AVR VR6 Voltage Regulator for Caterpillar Generator

 

Features

 

VR6 controls the DC exciter field power of conventional, 50 or 60 Hz brushless genera tors. The regulator(VR6) includes frequency compensation with selectable slope, inverse time over-excitation shutdown, solid-state build-up circuitry, single-phase or three-phase voltage sensing, single-phase or three-phase shunt, or permanent magnet power input, and parallel droop compensation, and an accessory input. The accessory input provides compatibility with accessories such as a var/power factor controller.

 

The K65-12B and K125-10B Voltage Regulators are contained in an encapsulated plastic case. The regulator controls the DC exciter field power of conventional, 50 or 60 Hz brushless generators.
